Problems stared because of the urban by-products of transport, industrial activities, and the overcrowding of human habitation
Asia’s urban profile increased from 27% (0.7B people) in 1980 to 38% (1.4B) in 2000 and will rise to 50% (2.3B) in 2020.
Deforestation/Desertification
This threatens food.
More than a third of the arable land in Asia is at risk for this.
Water
Water is increasingly polluted by untreated sewage, f industrial discharges, and from salt-water intrusion of overexploited water tables.
Over fishing
Marine’s catches increased from 17 million metric tons in 1950 to a peak of 87.1 million metric tons in 1996.
Steady increase in the frequency of clashes and incidents at sea caused by foreign fishing trawlers illegally encroaching into Exclusive Economic Zones and territorial seas.
Air Pollution
From vehicles, power plants, incinerators and industry.
Outdated pollution control technology and the use of high polluting fuels compound this problem.
Temperatures:very from over 100 degrees to below freezing. Monsoons winds influence much of the climate. Winters:Monsoons winds from the North blow, causing cold, dry weather. Summers: Monsoons winds blow from the seas, causing hot, humid weather. 1. Long and cold winters, cold wind from Polar Regions. 2. Widespread summers with short and hot highlands and little rain except in the mountains.
South East (Indonesia) – wet tropical climate
Up north (Russia) – colder almost polar temps.
West – dry and arid climates of Middle East.
Central Asia (China) – mountains and sub-tropic weather
Five Major Environmental Issues In Asia
Urban Excess/ Over Population
Deforestation/Desertification
Water
Over fishing
Air Pollution
- From vehicles, power plants, incinerators and industry.
- Outdated pollution control technology and the use of high polluting fuels compound this problem.
